Linux memory metricset
editLinux memory metricset
editThis functionality is in beta and is subject to change. The design and code is less mature than official GA features and is being provided as-is with no warranties. Beta features are not subject to the support SLA of official GA features.
The memory metricset extends system/memory and adds linux-specific memory metrics, including Huge Pages and overall paging statistics.
as of now, this data is part of system/memory on Metricbeat, but can only be found in the Linux integration in Fleet. In the future, this data will be removed from system/memory.
This is a default metricset. If the host module is unconfigured, this metricset is enabled by default.
For a description of each field in the metricset, see the exported fields section.
Here is an example document generated by this metricset:
